Description
Technical field
The present invention relates to a kind of sanitaryware forming mould and preparation method thereof, be specifically related to a kind of acrylic sanitaryware forming mould and preparation method thereof.
Background technology
Acrylic also is PMMA or polymethyl methacrylate, it is the Chinese call of English acrylic, chemical name is polymethylmethacrylate, it is a kind of exploitation important thermoplastics early, have the transparency, chemical stability and weathering resistance preferably, easy dyeing, easily processing, outward appearance is graceful, has a wide range of applications in construction industry.PMMA has light weight, inexpensive, is easy to the advantages such as moulding.The forming method of PMMA has casting, ejection formation, mechanical workout, thermoforming etc.
Acrylic is can make the best type material of sanitary ware after pottery.Compare with traditional stupalith, acrylic has high brightness; Good toughness, cracky not; Reparation is strong, as long as dipping in a toothpaste with soft foam just can be new with sanitary equipment wiping one; Quality is soft, there is no ice-cold sharp sense winter; Bright in luster, can satisfy the individual character of different grades and pursue.Make platform basin, bathtub, sitting wc pan with acrylic, not only style is exquisite, and is durable in use, and has environmental-protection function, and the radiation degree of its radiation and human body self bone is very nearly the same.
Because the products such as bathtub are moulded more complicated outward, has darker forming height, the material, mould and the mechanism that use with the ordinary packing material are difficult to satisfy processing requirement, are the good bases of sanitary equipment moulding so select suitable sheet material, mould and suitable equipment.
The moulding of acrylic sanitary equipment uses plastic plate molded usually, and described plastic plate mainly uses pure acrylic (methyl methacrylate) material or ABS matrix material, and recent thermoplastic material newly developed.
The production of acrylic sanitaryware is with the acrylic board thermoplastic, utilizes negative pressure of vacuum, acryl plates is adsorbed on forming mould and makes the sanitaryware of different shape.1. the preparation method of acrylic sanitary equipment mainly comprises the steps: design paper or the full pattern by the sanitary equipment moulding, Design and Machining plastics sucking moulding mould; 2. the acrylic board that cuts on request thermoplastic on plastic suction forming apparatus, the acrylic board after softening by mechanical compaction on mould; Under the condition that seals, by the suction of vacuum, make acrylic board tensile deformation in mould, be adsorbed on mold wall, start cooling blower, make acrylic board hardening moulding, turn off vacuum, suitably be filled with air, then use the mechanical way demoulding, product is taken out; 3. the stock after moulding is carried out resin and apply sticking the reinforcement, it is generally to be compounded in the bottom of sanitary equipment stock with unsaturated polyester and glass fibre that what is called is applied sticking, makes moulding product that enough intensity be arranged; 4. the product after deposited gluing after solidifying, begins to carry out the cutting edge cutting; 5. punching, reconditioning, mounting bracket.
In the preparation method of acrylic sanitary equipment, the plastics sucking moulding mould generally adopts aluminium alloy or resin mold to make.The aluminum alloy mould life-span is long, and operational characteristic is good, and appearance is highly polished, but because cost is high, the process-cycle is longer, and the application in the production of conventional sanitary ware product is subject to certain limitation.Resin die is because cost is lower, and the process-cycle is short, can satisfy the bathroom variety variations, uses comparatively extensive.But resin die mainly contain following shortcoming:
1, heat conductivility is poor: need very fast cooling and shaping after Workpiece shaping, but resin die is cooling slow, causes the workpiece demould time to extend, reduce production efficiency, when producing in the winter time simultaneously, mould need to be heated to certain temperature, the resin die temperature rise is slow, affects equally production efficiency.
2, easily produce static, absorption micronic dust impurity: due to the electrostatic adhesion effect, airborne impurity micronic dust is adsorbed in die surface, directly affects the surface quality of acrylic product.
3, the resin physical strength is low, and is not wear-resistant, and need to there be a certain size circular arc the mould nook, and the product that straightedge line appearance requirement is arranged is difficult for manufacturing.
4, the resin die life-span shorter, the lifting repeatedly of the temperature in production process, die surface produces the finedraw of chapping, and affects quality product.
5, mold integral easily produces creep, affects the form accuracy of product.
Therefore, there is a need in the field to provide a kind of plastics sucking moulding mould for the preparation of acrylic sanitary equipment, described mould should have operational characteristic preferably, and appearance is highly polished, and cost is low, and the process-cycle is short; And have good thermal conductivity, be not easy to produce static, be difficult for the absorption dust, physical strength is higher, and is wear-resistant, and life-span length and mould are difficult for occuring the characteristic of creep.
Summary of the invention
For the deficiencies in the prior art, one of purpose of the present invention is to provide a kind of forming mould of sanitaryware, and the operational characteristic of described mould is better, and appearance is bright and clean, cost is low, process-cycle is short, and has good thermal conductivity, is difficult for producing static, be difficult for the absorption dust, have higher physical strength, wear-resistant, long service life.
The present invention is achieved through the following technical solutions:
A kind of forming mould of sanitaryware, the material of described mould is mixed to get by light-cured resin and metal-powder.
The material of the forming mould of sanitaryware of the present invention combines the advantage of aluminium alloy mould and resin mold, and has overcome its shortcoming separately, for the forming mould of sanitaryware provides a kind of new selection.The effect of metal-powder is to make the forming mould of sanitaryware have physical strength preferably, and can process the product of corner angle; Increased the thermal conductivity of forming mould, static resistance, the life-span is long, be difficult for creep occurs, and the working accuracy of product is high; The cost of sanitaryware provided by the invention is lower simultaneously, and the process-cycle is the same with the ordinary resin mould, and is shorter than aluminum alloy mould.
